Linear Charge Management Li-Ion/Li-Pol Packs 750mA 4.2V 10-Pin VSON EP T/R, BQ24085DRCR, Texas Instruments

The bq24085/6/7/8 series are highly integrated Li-Ion and Li-Pol linear chargers, targeted at space-limited portable applications. The bq24085/6/7/8 series offers a variety of safety features and functional options, while still implementing a complete charging system in a small package. The battery is charged in three phases: conditioning, constant or thermally regulated current, and constant voltage. Charge is terminated based on minimum current. An internal programmable charge timer provides a backup safety feature for charge termination and is dynamically adjusted during the thermal regulation phase.The bq24085/6/7/8 automatically restarts the charge if the battery voltage falls below an internal threshold; sleep mode is set when the external input supply is removed.Multiple versions of this device family enable easy design of the bq24085/6/7/8 in cradle chargers or in the end equipment, while using low cost or high-end AC adapters.

  • Ideal for Low-Dropout Designs for Single-Cell Li-Ion or Li-Pol Packs in Space Limited Applications
  • Integrated Power FET and Current Sensor for up to 750-mA Charge Applications
  • Reverse Leakage Protection Prevents Battery Drainage
  • ±0.5% Voltage Regulation Accuracy
  • Thermal Regulation Maximizes Charge Rate
  • Charge Termination by Minimum Current and Time
  • Precharge Conditioning With Safety Timer
  • Status Outputs for LED or System Interface Indicate Charge, Fault, and Power Good Outputs
  • Short-Circuit and Thermal Protection
  • Automatic Sleep Mode for Low Power Consumption
  • Small 3×3 mm MLP Package
  • Selectable Battery Insertion and Battery Absent Detection
  • Input Overvoltage Protection
    • 6.5 V and 10.5 V Options
  • APPLICATIONS
    • PDA, MP3 Players, Digital Cameras
    • Internet Appliances and Handheld Devices
